Please help me compute standard deviation! Here is the problem, as written. what is the income distribution of super shoppers. In the following table, income units are in thousands of dollars, and each interval goes up to but does not include the given high value. The midpoint are given to the nearest thousand dollars. Income range: 5-15, 15-25, 25-35, 35-45, 45-55, 55 or more. Next line is Midpoint x: 10, 20, 30, 40, 50, 60. Last line is percent of super shoppers: 21%, 14%, 22%, 15%, 20%, 8%.

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
